Distribution
Use in jewelry
The new wave of Victorian Egyptomania following the opening of the Suez Canal in 1869 increased the demand for Egyptian jewelry, especially scarabs. This, combined with an increased interest in the natural world, lead to the import of Polychalca punctatissima carapaces from South America for use in jewelry as "scarabs".[1][2]
